I know you all know but, just a reminder :

package main

import "fmt"

func main() {
  var m = 0.1
  var n = 0.2
  fmt.Println(m + n)

  var a = 0.1
  var b = 6.0
  fmt.Println(a * b)

  var o = 0.6
  var p = 0.3
  fmt.Println(o + p)

  var f = 1.39
  fmt.Println(f * f)

  const c = 1.39
  fmt.Println(c * c)
}

0.30000000000000004

Reducing Cognitive load (Golab2022 notes) in code :

• Line of Sight : 1st level, second level for error conditions
  • eliminate else, return early, avoid extra nesting, wrap in function
  • align the happy path
  • remove misterious booleans
• Package Names : concise and clear, move on the calling side. No util/common/ packages, split
• Pure functions as much as possible
• pass with & to indicate we change the object
• Don’t lie to the reader

Perche’ l’innovazione e’ cosi’ difficile in italia : qui

Questo non vale solo per la digitalizzazione, vale per l’industrializzazione e per il capitalismo. Prendo in prestito la domanda (e la risposta) di Roberto Maragliano “Perché i temi della maturità sono ancora così? Ce lo dice Camillo Olivetti (padre di Adriano) in un appunto del 1927: “L’istruzione della nostra borghesia ha un fondamento prettamente anti-industriale. Noi siamo ancora i figli dei Latini che lasciarono ai servi e ai liberti i lavori industriali e che in ben poco conto li ritennero, tanto che ci tramandarono i nomi dei più mediocri proconsoli e dei poetucoli ed istrioni che dilettarono la decadenza romana, ma non ci ricordarono neppure i nomi di quei sommi ingegneri che costruirono le strade gli acquedotti e i grandi monumenti dell’Impero Romano” (da Paolo Bricco, Adriano Olivetti, un italiano del Novecento, Rizzoli, appena uscito)”.

Interesting :

Super, 10X, rockstar — these are names for developers who produce a lot of code or work in many development areas. Such developers sometimes build a reputation — and an ego. “These super developers usually make their code unnecessarily complex just because they can,” Rials said. Other team members struggle to comprehend and edit the complex code. These colleagues might even compliment the super developer about the code’s complexity, which encourages more of it. Businesses should empower junior developers to take a fresh look at code.
